The mayor announced a deal for California Pacific Medical Center construction, the largest private hospital construction project in San Francisco history, with great fanfare. The big winners are the landlords and speculators. The centerpiece of this goes to one of the biggest issues in this crowded city: Jobs and housing costs. The mayor talks about jobs all the time—he's the "jobs mayor, jobs jobs jobs." Which is popular when unemployment remains stubbornly high. But there's a flip side: If you create a lot of jobs that attract new residents to the city, and you don't build housing that's affordable to those workers, you put additional pressure on the existing housing stock, driving up costs for everyone.
